Following a failure to capitalize on a recent price recovery, bitcoin could be in for another sharp sell-off, the technical charts indicate.

The cryptocurrency found a temporary low of $8,371 on March 9 and jumped above $9,000 in a convincing manner on March 11, according to CoinDesk's Bitcoin Price Index (BPI). However, the corrective rally seems to have stalled over the past few days.

The cryptocurrency has spent a better part of the last 48 hours moving in a sideways manner in the narrow range of $8,800–$9,400. As of writing, the BPI is seen at $9,095 – down 0.5 percent for the session.

Notably, trading volume has dropped more than 50 percent since March 9, possibly indicating a lack of confidence among traders in the sustainability of the corrective move higher. Should bitcoin see a decisive move above $11,700 (recent high), volumes are likely to climb.

For now, however, the price chart analysis indicates an increased risk of a sell-off to the lows seen in February.

The above chart (prices as per Bitfinex) shows:

Despite the long-tailed doji candle and a bullish outside day reversal, bitcoin has not been able to scale the $10,000 mark. More importantly, it has repeatedly failed to hold above the double-top neckline resistance (former support) of $9,280. So, yesterday's doji candle likely shows bullish exhaustion rather than indecision in the marketplace.

Further, the 10-day moving average (MA) continues sloping downwards in favor of the bears.

Hence, the probability of a downside break of the inverted (bear) flag pattern (seen on the 4-hour chart below) is high.

A downside break of the bear flag would signal a continuation of the sell-off from the recent highs around $11,700, and could yield a drop to $5,500 (target derived by subtracting the height of the flagpole from the eventual breakdown level, i.e. flag support).

It's also worth noting that a downside break of the inverted flag would only add credence to the bearish weekly relative strength index.

The probability of bitcoin prices falling below $8,600 (flag support) has increased. A bear flag breakdown could open doors for a drop to $6,000 (February low) and $5,500 (bear flag breakdown target).

On the higher side, only a daily close (as per UTC) above the 10-day moving average (currently seen at $9,619) would signal bearish invalidation.

A convincing break above $11,700 (recent high) will signal a bearish-to-bullish trend change.
